“He looked out, he saw that many of the people who perpetrated the Paris atrocities, many of them had come from Brussels,” he added.

“He has business friends who go to and from the European Union in Brussels, and his business friends are saying to him, ‘it’s out of control.’ So [Trump] says the obvious, [and] everybody else thinks he’s stupid because he’s the only one saying it. The fact is, Donald Trump was right.”

After the attacks, Trump doubled down on his calls to close America’s borders. On Wednesday, he said that Muslims themselves need to do more to prevent terrorism:

“When they see trouble, they have to report it. They are not reporting it; they are absolutely not reporting it, and that’s a big problem,” Trump said when asked what his message was for British Muslims following attacks in Brussels.

“It’s like they’re protecting each other, but they’re really doing very bad damage, and they have to open up to society. They have to report the bad ones.”
